The VR-4 has been stuttering while cold for the last five or six months. Only when it's sat overnight and started in the morning. Felt like it was missing; checked intake tract, no leaks, ECU has had its capacitors replaced, plugs and wires are fine. Couldn't figure it out.
Today I started it after it sat a couple days (from the busted wheel) and took it out, and it did its usual stuttering business. I was watching the logger and saw nothing odd, so I floored it and the car began to accelerate and then the power fell way off and the stuttering went through the roof; then I looked out the rear view and saw the huge cloud of black smoke
Something is definitely make the car run EXTREMELY rich when cold. Once it heats up it runs fine. Anyone see this behavior before and fix it?
